Definitions

  • the present invention relates to an easy to use dispenser for liquid products, comprising a liquid holding reservoir connectable to a chamber for holding liquid under pressure and in turn connected to a spray arrangement for spraying the relevant liquid.
  • the system of the invention is intended for the spraying of liquids selected from pesticides, such as herbicides, insecticides, fungicides, and others, house-hold cleaning products including for instance detergents, window cleaning products, carpet cleaning products or similar.
  • Dispensers are generally well known in the art.
  • Prior art dispensers of the general type typically include a bottle and a dispensing mechanism, for instance a trigger sprayer.
  • the trigger sprayer may be attached to the bottle in any conventional way, e.g. by a threaded connection, a bayonet connection or a snap connection.
  • Such trigger sprayers are well known in the art.
  • a problem with such dispensers is that those containers, when completely filled or filled to a substantial extent, are mostly uncomfortable to use as a result of the weight of the liquid contained therein. Also, most of these dispensers are intended to be used once and thrown in the waste when empty.
  • Known dispensers include squeeze bottles made of a rather flexible material and connected to a spray nozzle.
  • the liquid contained in the bottle is pressurized by the squeezing of the bottle and liquid is released through the nozzle.
  • Such arrangement is very simple and of low cost but leads to irregular spray patterns and leakage.
  • the liquid containing bottle is a more rigid bottle and pressurized by pumping air into it.
  • the liquid under pressure then may be released through the sprayer.
  • the spray pattern is not constant as it changes along with pressure reduction in the bottle in the course of use. Also, these equipments are generally rather heavy and inconvenient to use.
  • a re-usable spray arrangement that includes a trigger sprayer on refill packs.
  • the refill packs need to comprise appropriate connection means and be of the appropriate shape, thus of relatively high cost and more likely to be less environmentally friendly than one-way refill packs.
  • Such arrangements comprising trigger sprayers further require the user to accomplish inconvenient pumping actions with his or her finger and the spray volume per pumping movement is rather small, mostly around 1 ml.
  • EP-0814913 discloses a pump sprayer apparatus intended for being mounted on a liquid supply container suitable to contain pesticides, detergents or other liquid chemical compositions.
  • the sprayer apparatus comprises a pump assembly, such as a positive displacement pump with a piston reciprocally movable in a cylinder, an inflatable accumulating bladder and a dispensing assembly.
  • the piston raised by the user draws liquid from the supply container into the cylinder and then, when movement is reversed, pushes the said liquid into the inflatable bladder which accumulates the liquid under pressure.
  • the energy accumulated into the expanded bladder may then be transferred to the liquid in an essentially constant manner when released from the bladder for discharge through the sprayer.
  • One of the disadvantages of that system though is that it needs to be combined with a rather rigid supply container.
  • the volume of the liquid ready to be dispensed through the sprayer is relatively small, thus allowing for a reduced number of sprays.
  • the present invention now seeks to provide a dispenser for liquid products selected from pesticides, such as herbicides, insecticides, fungicides, and others, house-hold cleaning products including for instance detergents, window cleaning products, carpet cleaning products or similar.
  • pesticides such as herbicides, insecticides, fungicides, and others
  • house-hold cleaning products including for instance detergents, window cleaning products, carpet cleaning products or similar.
  • the invention dispenser is easy to operate and of convenient use, while allowing for a comfortable spray volume prior to each recharging (in other words showing higher autonomy), more specifically adapted to the relevant use of the equipment.
  • the dispenser of the invention for liquid products comprises
  • the liquid holding reservoir may be a flexible, one-way refill pack. It may be connected to the pump arrangement by a flexible tube and a one-way valve that allows flow of liquid solely from the reservoir to the pump, thus avoiding liquid to escape from the pump. Or the pump arrangement can be connected directly to a one-way valve/closure on the liquid holding reservoir.
  • the pump arrangement comprises a cylinder of essentially circular section, one end of which is connectable to the liquid holding reservoir through a one-way valve that allows flow of liquid solely from the reservoir to the pump, and is further connected to the chamber through a one-way valve preventing liquid to flow from the chamber back into the pump cylinder, and a piston slidably mounted in the cylinder in a liquid tight manner, the piston being assembled with a rod extending through the opposite end of the cylinder into a handle for operation by the user.
  • the dispenser represented schematically in Figures 1 to 4 constitutes a first embodiment of the invention.
  • the dispenser 10 comprises a removable liquid holding reservoir (not represented) that can be connected to it under 2 by way of a flexible tube 1, an essentially rigid chamber 20 for holding liquid under pressure and comprising a spring 22 acting on a piston 24 arranged at the bottom of the cylinder to place liquid injected into said chamber 20 under pressure, a pump arrangement 30 for pumping liquid from the liquid holding reservoir (not represented) into the said chamber 20 for holding liquid under pressure, the pump 30 being connected to the chamber 20 through a conduct 32 which incorporates a one-way valve (see description with respect of Figure 7 herein below), thus preventing liquid to flow from the chamber under pressure 20 back into the pump arrangement 30.
  • the chamber 20 is in turn connected to a spray nozzle 40 through a valve 42 controllable by the user by exerting pressure on a trigger button 44 for spraying said liquid stored in chamber 20.
  • the flexible tube connection 2 may advantageously be arranged at the top of the chamber 20, preferably right underneath the nozzle 40.
  • the spring and the piston may be arranged at the top of the chamber 20 and the tube connector 2 is arranged at the bottom thereof.
  • this connector may also be placed at a location at the bottom of the chamber 20 or at the bottom of the handle.
  • the connector 2 may include the one-way valve 3 allowing liquid to flow from the external container to the pump 30 and preventing liquid to flow back into the liquid holding reservoir.
  • the dispenser 10 may advantageously be equipped with a handle 50 designed in such a way so as to facilitate holding of the device and spraying on target surface in ergonomically advantageous position or inclination. More specifically in the case of a dispenser of pesticides intended to be sprayed on target pests, such as weeds, the handle 50 may be inclined such as to ease directing the whole device loaded with liquid in a downward position.
  • the pump arrangement 30 comprises a cylinder 34 with a piston 36 of essentially circular section.
  • One end of cylinder 34 is connectable to the liquid holding reservoir through a one-way valve 3 that allows flow of liquid solely from the reservoir to the pump 30, and is further connected to the chamber 20 through a one-way valve 32 preventing liquid to flow from the chamber 20 back into the pump cylinder 34.
  • the piston 36 is slidably mounted in the cylinder 34 in a liquid tight manner, and is assembled with a rod 38 extending through the top end of the cylinder 30 into a handle 39 for operation by the user.
  • the pump is arranged in an essentially parallel fashion to the cylindrical chamber 20 and adjacent to it.
  • the handle 39 is arranged at the top of the dispenser or, expressed differently, at the same side as the spray nozzle 40.
  • Figure 7 schematically represents the flow of liquid and shows the operation of the one-way valves.
  • one-way valve 3 When generating a depression in the pump cylinder 38, one-way valve 3 opens to allow flow of liquid from the liquid holding reservoir 1 into the pump cylinder according to flow direction a.
  • One-way valve 32 is closed by the depression.
  • valve 3 When expelling the liquid with the pump piston 36 according to flow direction b, valve 3 closes because of the pressure acting on the side of the pump but one-way valve 32 opens and allows flow of liquid into chamber 20 where said liquid is maintained under pressure.
  • liquid under pressure may escape along direction c and finally d through nozzle 40.
  • Chamber 20 may be designed to contain an adequate volume, thus giving the dispenser a reasonable autonomy. In the case of use for pesticide application, more specifically herbicide application, a volume of approximately 200 to 600 ml is advantageous.
  • the volume of the pump arrangement 30, i.e. cylinder 34, is preferably adapted to the volume of the chamber 20, in order for the user to fill chamber 20 after preferably 4 - 10 pumping operations.
  • One of the advantages of the invention arrangement is that the liquid to be sprayed is maintained in chamber 20 under an essentially constant pressure, thus allowing the user to preserve an essentially equal spray pattern all along the spraying operation.
  • Another advantage of the invention consists in the fact that the user bears a relatively light equipment with reasonable autonomy.
  • Refill packs may be provided that are more environmentally friendly and need not consist in rigid containers.
  • the invention equipment allows to conceive a liquid holding container for instance made of a flexible plastic bag with a rather small connection for tube 1.
  • Several volumes may be provided for, e.g. 1 I, 2 I, 5 I and more.
  • Such containers may be filled with so-called ready-to-use spray solution.
  • One may also provide for containers partially filled with a concentrate and that allow top-up with water or other diluents, thus allowing for reduced transportation costs and energy resources.
  • Nozzle 40 may advantageously be mounted on an essentially rigid tube also called lance 41 which in turn is advantageously slidably mounted in casing 11.
  • grips 45 may be fastened to the lance, advantageously on both sides thereof, and extend through casing 11 in order to facilitate the sliding of said lance 41.
  • the grips 45 interact with trigger button 44 in order to provide a child-safety arrangement.
  • said grips may block movement of the trigger button 44 and thus prevent opening of the release valve 42.
  • the trigger button 44 is released and may be operated as appropriate in order to release liquid through the spray nozzle 40.
  • both grips 45 are in the form of a click assembly that snap into a counterpart on casing 11 in several (intermediate) locked positions of the lance 41 and that require pressure on one part of each grip 45 or a squeezing action to slightly buckle the relevant grips 45 or their link to the lance 41 in order to release said click assembly.
  • the dispenser 110 comprises a removable liquid holding reservoir (not represented) that can be connected to it by way of a flexible tube 101, an essentially rigid chamber 120 for holding liquid under pressure and comprising a spring 122 acting on a piston 124 to place liquid injected into said chamber 120 under pressure, a pump arrangement 130 for pumping liquid from the liquid holding reservoir (not represented) into the said chamber 120 for holding liquid under pressure, the pump 130 being connected to the chamber 120 through a conduct which incorporates a one-way valve, thus preventing liquid to flow from the chamber under pressure 120 back into the pump arrangement 130.
  • the chamber 120 is in turn connected to a spray nozzle 140 through a release valve 142 controllable by the user by exerting pressure on a trigger button 144 for spraying said liquid stored in chamber 120.
  • the pump 130 is arranged in the form of a handle slightly inclined compared to the axis of the cylindrical chamber 120 and detached from it, while connected at the top end to the chamber 120 and the handle 139 extending through the opposite end of the pump.
  • the tube connector 102 is then preferably arranged at the top of the cylindrical chamber 120.
  • the nozzle 140 then is arranged at the top of the pump, right next to the connector 102.
  • the dispenser 110 does not need a separate handle as the pump arrangement 130 is in the form of a handle already.
  • the inclination of pump arrangement 130 and possibly of the spray nozzle 140 both compared to the axis of the essentially cylindrical chamber 120 may be designed in such a way so as to facilitate holding of the device and spraying on target surface in ergonomically advantageous position or inclination. More specifically in the case of a dispenser of pesticides intended to be sprayed on target pests, such as weeds, the inclination will be such as to ease directing the whole device loaded with liquid in a downward position.
  • the connector 102 may be arranged at the bottom of the chamber 120 or at the bottom of the handle.
  • the embodiment of Figures 5 and 6 does not allow pumping operation when resting in upright position on a surface.
  • Handle 139 needs to be pulled out downwardly to generate a depression in the pump for extracting liquid from the liquid holding reservoir. Pushing the handle 139 back into the handle pushes the liquid into chamber 120. The pressure of the liquid pushes piston 124 down, thus compressing the spring 122. The energy stored in the spring allows to maintain the liquid under an essentially constant pressure in the chamber 120. The user may repeat the same operation several times until the chamber 120 is essentially full. One may then disconnect the device 110 from the liquid holding reservoir for instance by unscrewing or unplugging tube 101 at its connection 102 with the dispenser, and use the dispenser to apply the liquid as appropriate.
  • nozzle 140 bearing lance may be longer as it may easily be arranged in parallel to either the pump 130 or chamber 120.
  • the connecting tube schematically represented with flow direction d then needs to extend up to the end of the lance opposite nozzle 140.
  • nozzle 40 bearing lance 41 is shown in retracted position, blocking with corresponding grips 45, and possibly an extension thereof, the movement of trigger button 44, thus preventing release of spray liquid through release valve 42.
  • the tubular connection (d) is shown in a schematic way.
  • the nozzle 40 bearing lance 41 has been shown in extended position, the grips thus liberating button 44 which may thus be operated to spray liquid.
  • the grips 45 slide in the casing which has been omitted for the sake of clarity.
